To all whom it may concern:

Processes for Treating Gum,

citizen of the United lldartford, in the county of following lihis invention relates to the treatment of ic g urns which in their raw connnercial'conditioncontain more or less bark, small stones and other foreign s1 bstances that must be thertreatment. peoia'lly adapted to the treatment of chicle removed in order to fit the gums for. fur- The invention is more es.

which is to be used in the manufacture of chewing gum. In order to'free the nude degree of heat as is ,sirable matter at sirable matter the gum is generally melted, but ohicle cannot be heated to such a degree as to render it a perfect liquid without deleteriously afiecting its quality "for subsequent use in chewing gum. Consequently it is desirable to subject chicle to as possible in order to'accomplish the desired end.

The object of this invention is to provide means for continuously, rapidly and efiiciently rendering hardenedchicle gum molten and removing the bark and other undeas low a temperature as possible so as not to injure the quality of the m in attaining this end a machine is designed having mechanism which reduces the m to a semi-fluid state and at the same time disintegrates the foreign substances and passes the mass in a continuous viscous stream to mechanism which picks out the undesirable solid particles and forces the cleargum through a strainer, from which it is'ldischarged in a continuous stream fit for further use.

3 for heating it andv keeping the gum warm. In this hopper are two rotating cylinders l provided on their peripheral surfaces with cutting grooves 5. These cylinders are hollow so that they may be heated by'steam admitted through the pipes 6; y The bottom plates 7 ofthe hopper are shaped to closely conform to the cylinders, except below the line of contact between the cylinders, and the cylinders are provided with gears 8 by means of which they may be rotated toward eachother at 'difierent rates of speed. Adjacent to the cylinders and with their edges in contactwith the peripheral wall thereof, below the meeting line, are scrapers A CORPORATION OF NEW PatentedApL1G, 1918. Application filed September 8,1916. Serial No. 119,035, I Z i i 9 which are mounted on the hollow boxes 10 that may be heated by means of steam admitted through pipes 11. Gum placed in the hopper is melted by the abrasion of the moving heated surfaces of the cylinders, and the particles of solid matter are disintegrated and reduced by the grinding action of the cylinders as such matter passes down with the molten gum between Owing to the friction of the heated surfaces of the cylinders the gum is. rapidly made molten at a comparatively low degree of temperature, audit is crushed togetherw'ith the solid particles as it passes betweenthe cylinders so that the molten mass flows down onto the trough 12 below the cylinders in a continuous viscous stream.

In the frame below the melting means is a hollow rotatory cylinder 13. The peripheral Wall of this cylinder is provided .with perforations 14c, and covering the perforations is a screen 15 formed of very fine mesh. A pulley or gear 16 may be arranged on the shaft of this cylinder for rotating it. In the cylinder is a scraper 17 This scraper is hollow 'so that steam may be admitted into the interior from the pipe 18, and it is held stationary so that its edge 19 willscrape the gum from the interior of the cylinder. wall as the cylinder rotates. .5";

Above and bearing upon the screened surface ofthe cylinder is a rubber covered roller 20. This 23 are attached to this shaft and the outer ends of these levers are drawn downward by springs 24:. Cams 25 are arrange limit the downward movement of the lethe cylinders.

roller is'supported by arms 21 that are attached to the shaft 22. Levers vers and thus regulate the pressure of the lever upon the cylinder. ,Fastened to the arms 21 that are mounted on the shaft 2:2

18 a scraper 27, the lower edge of which is designed to engage the roller along the top,

col'der yielding surface picks out the solid particles and carries them around until they are collected by the scraper at the top, from which locality they may be removed by any suitable means. The clear gum, which'is scraped from the interior of the cylinder, is directed. by the scraper to the end of the cylinder, where it escapes through the spout 29 to the receptacle 30:
